ments in Three-Wheel Riding-Flows, of which the following is a specification. 7

My invention consists of contrivances for the mounting of the plow on the saddle or beam of a three-wheel riding-plow having a cranked front axle and main wheels, with a rear caster-wheel, in an arrangement enabling the plow to be lowered into and raised out of the ground by the sliding of the stock in vertical ways of the beam or saddle, with suitable toothed rack, pinion, lever, and friction-roller mechanism for so operating the plow, by which more substantial and efficient apparatus may be employed than when the beam or saddle is made to rise and fall for the purpose; and my invention also consists of improvements in the tongue, colter, and evener apparatus for greater simplicity and efficiency, all as hereinafter fully described, reference being made to the accompanying drawings, in which- Figure l is a side elevation with the landside wheel removed by the section of the axle on the line as x of Fig. 2. Fig. 2 is a plan view, with some parts in section. Figs. 3, 4, and 5 are details, on an enlarged scale, of the plow-connection, with the saddle or beam in side elevation, plan, and in front elevation and transverse section of the beam at y 11 Fig. 6 is a section of the pivot-joint of the caster-wheel. Fig. 7 is a detail of the beam contrivan ce. V

For the beam or saddle a, I use an angle-bar, making asocket, b, at the rear end for the pivot- I stock 0 of the caster-wheel cl, and fork-arms e at the front end, with bearing holes or sockets by which to mount it on the cranked axle f of the main front wheels, 9, and about midway between the'front and rear ends of this beam or saddle I provide the vertical slideway h in one side of the beam for the stock i of the plow j, which I fit in said slideway suitably for being shifted up and down and for being held firmly at any point with friction-rollers 7c and Z, suitably located in said slideway to take the thrusts of the front and back edges of the stock, respectively, and relieve the friction of the slide, thus providing a simple contrivance for the mounting of the plow, so that it may be adjusted on the beam in a simple way, instead of adjusting the beam on the axle, and enabling the beam to be connected to the axle without adjustment other than the turning of theaxle in the bearings of the beam.

The beam at is constructed with a vertical extension, m, above and below for suitable breadth to afford substantial holding for the plow-stock, in which the slideway is placed under the solid lip n at one side, and for the attached retainingcleat 0 of the other side, the said extension being made thicker on the side having the solid lip it than on the other side, to provide for said solid lip and also for the substantial support of the friction-roller Z and the pivot o of the pinion :0 and ratchetwheel y, by which the stock is in this example to be worked. For the attached retaining cleat 0 of the other side of the slideway of the plow-standard I utilize one edge of the rackplate 5, employed for locking the shiftinglever tby the stop-latch u, to hold the plow when set, said plate being applied so as to overlap the slideway suitably for such cleat, and it is secured by the bolts 1;, one of which forms the pivot of friction-roller 7c, which is fitted in a recess of extension at under the rack-plate.

The plow-stock is in the present case provided with arack-plate, w, that gears with the pinion a: on the pivot o",which pinion is turned by the ratchet-wheel 1, also attached to said pivot, and provided with the levert and latch z for shifting it, and with the dog a for holding it, said dog being pivoted to the beam at b and the lever being pivoted loosely on the pivot 0 The lever t and latch z are used in some cases for holding the plow in position without the dog a, and particularly for shifting the plow up or down through a short range to vary the depth of the furrow to some extent, the lever being set along the rack s and held in it by the latch u, which, together with the latch z, is connected to one trip-handle c of said latch to, so that a partial throw of the trip-handle will detach latch a and leave latch z engaged with the ratchet, to allow the lever to swing and shift the ratchet, and a further the lever, but on a greater radius than that of movement of said trip-handle will detach both latches when latch z is to be shifted along the ratchet-wheel for greater shift of the plowstock, the ratchet then being held by the dog a.

It is obvious that a lever having a toothed segmental arm gearing directly with the rack w may be substituted for the pinion 3/ and its ratchet mechanism if desired. The contrivances of the guidcway may also be modified if desired.

For shifting the cranked axlej, to adjust the furrow-wheel for the furrow or for the surface, the tongue d, which is mounted above the axle by the bearing-bar a, holding it a suitable distance above the axle, is provided with a segmental toothed holding-rack, f, and the lever g is rigidly attached to the axle suitably for swinging along the rack, and provided with the stop-latch 7t, engaging the rack to hold the lever and the axle at any position along the rack. The tongue is pivoted to the front end of the bearing-bar e at 6 and connected to the rear end of said bar by the slotted and toothed arm f, the bolt being adapted to shift in said slot by the stop-latch h so that by releasing the stop-latch the tongue can swing to some extent to relieve the lateral stress. In this case the arrangement is represented for turning the team to theleft hand only, which is generally the way the team turns; but I contemplate arranging it to turn either way.

The revolving colter i is pivoted in the forked arm j, extending rearward from the joint is, with the lower arm of a lever, Z, pivoted on the axle and extending downward and forward to said joint k, and having a latch, m, that engages the sector m, attached to the axle for setting the colter higher or lower by swinging the lever accordingly. The joint In is adapted for shifting the colter laterally to set it in alignment with the plow.

For a dust-proof and durable pivot-joint of the caster-wheel I make the hub a with the countersunk cones p and shoulders g at the bases ofthe cones, and provide the reverselyshaped caps 3, adapted to fit snugly on the shoulders q, also on the sides of the cones and in the countersunk sockets of the cones, and secure said caps by the pin it and the bosses to of the forked stock 0, the pin, which is secured in the hub by casting the hub on it, extending through the caps and entering into sockets ofthe bosses, the arms of which spring the bosses into sockets w in the exterior of the caps and onto the ends of the pin, thus making a joint that is constantly pressed tight by the spring of the arms of the fork without the use of any nuts, keys, or other devices adapted to wear slack. The bosses of the forked arms constantly bear on the metal at the bottoms of the sockets, where the contact is between the rotating and the stationary parts, and prevent the dustfrom working farther into the joint.

For attaching the evener by a contrivance enabling the point of connection to be shifted laterally, as maybe required,for regulating the draft, and at the same time being simple to construct and substantial in wear, I make a yoke or bow, at, of somewhat more than half a circle, and pivot it on the axle at 9 each side of the beam between the saddle-bearings on the axle, with arms 5, extending backward from the axle under the saddle-arms and connected thereto, for supporting the yokein the horizontal position, and about midway be tween the axle and the front end of the yoke I arrange the attaching-bar a on the arms of the yoke and parallel to the axle, and having aseries of clevis-pin holes, b", at intervals along it, in which to connect the cveneras required.

The axle turns in the bearings of the yoke, and the arms of the yoke, being connected to the arms of the saddle, maintain the yoke in the required horizontal position without interference of the axle by turning to adjust the crank.

Although I have described and represented avertical slideway for the plow-stock, I do not mean to be limited strictly to the vertical direction, for it is obvious that it may be more or less inclined without detriment for my purpose, and my invention includes any practical inclination.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
